"""
Unified evaluator script.
Features:
- Interactive selection of:
* model source (Mistral-SK variants / predefined models / manual path)
* GPU (via CUDA_VISIBLE_DEVICES)
* dataset source (local load_from_disk / HuggingFace dataset)
* number of prompts and generation parameters
- 4-bit loading (BitsAndBytes)
- Refusal detection + prompt-echo stripping
- Outputs: responses.txt, responses.json, summary.txt
